Another comes from the New York–based jeweler Kentshire, which also sells at Opening Ceremony and Bergdorf Goodman.

Didier Ltd. Unique Surrealist Hand Ring. Salvador Dali. United States. c. 1950s. 18k yellow gold, cut rubies, and diamonds.
Price: N/A.
This ring belonged to Mildred “Tweet” Kimball (d. 1999), a “bejeweled fixture of Denver high society and political circles.” She was on the board of the Denver Art Museum as accession chairman for 14 years and had her own vast and eclectic art collection, which she housed in a re-created Scottish castle on her “Cherokee Ranch” estate. She entertained her other passions there: wildlife conservation and cattle breeding.
Kimball married four times — this ring dates back to her first marriage to Merritt Ruddock, the scion of an aristocratic family with political connections, from 1938 to 1955. He was a member of the U.S. diplomatic corps and an obscure CIA official.
